Summary
Amitriptyline is used to treat depression, which is a mood disorder causing persistent sadness, and certain types of pain like neuropathic pain, which is pain from nerve damage. It can also help with chronic pain and migraines, which are severe headaches.
Amitriptyline works by increasing levels of chemicals like serotonin and norepinephrine in the brain, which are substances that help improve mood and reduce pain. Think of it like turning up the volume on a radio to get clearer sound.
Amitriptyline is usually taken once daily, often in the evening or at bedtime, because it can cause drowsiness. The starting dose for adults is typically 25 mg to 50 mg per day, with a maximum of 150 mg per day. Always follow your doctor's instructions.
Common side effects of Amitriptyline include dry mouth, which is a lack of saliva, drowsiness, which is feeling sleepy, and dizziness, which is feeling unsteady. These effects occur in more than 10% of users and are usually mild to moderate.
Amitriptyline can increase the risk of suicidal thoughts, especially in young people. It should not be used if you are allergic to it or have recently had a heart attack. Avoid alcohol, which can increase drowsiness, and always discuss your medical history with your doctor.
